CLOSURE FOR BOTTLES AND OTHER CONTAINERS.

Application filed October 11, 1926, Serial No.

This invention relates to improvements in closures for bottles and other containers and has for its object a closure that may be rapidly secured in position and which is particularly adapted for use on petrol tanks and cans.

According to this invention a closure comrises a resilient disk formed with a numer of peripheral fingers while the interior of the .mouth of the neck of the container is of a size to be frictionally engaged by the fingers or is provided with a ledge on which the ends of the fingers rest; the sides of the fingers being adapted to be sprung into firm engagement with the internal wall of the mouth of the container by deformation of the disk member which has a central bulged portion capable of being sprung into release and secure positions, the first of which is above and the second below the horizontal.

A knob or its equivalent is preferably formed on or attached to the central portion of the disc when it is desired to provide a permanently operable closure which s capable after removal from the container of being replaced thereon whenever desired.

According to a further feature of this invention an outer cap may'be provided connected to the disk by the shank of a knob secured to the latter and on which it has limited movement corresponding to the displacement of the central bulged portion, said cap forming a cover adapted to lie on the rim of the neck of the container. The cap member may consist of a flat or flanged cap, and in the latter case a Washer is preferably provided located against the flange in order that in some cases the closure when first applied may form an airtight seal.

According to another feature of this in Vention the peripheral fingers of the re silient disk are flanged, said flanged portions being adapted to engage a groove in the neck of the container or the like in which case the neck of the container may be undercut to form a groove above the ledge.

It will be seen that such a closure is capable of a number of applications, and for instance may be used for sealing milk bottles. potted meat jars where it is particularly useful in that the jar may be effectively resealed when once the jar has been opened.

The invention is illustrated in the accompanying drawings in which Figs. 1 and 2 are diametral sections of a disk in the release and secure positions.

140,953, and in Great Britain July 14, 1926.

Fig. 3 is a similar view of the disk in the container in the secure position.

Fig. 4 is a similar view but showin the disk provided with an outer cap, and the neck of the container with ledge and an undercut groove.

Referring to the drawing a is a disk formed with a. number of peripheral fingers b. c is the mouth of a container. The disk has a bulged portion 03 to which is connected an operating knob or handle e.

Referring now to Fig. 4 the disk a has attached to it a shank f on which is formed the operating knob or handle e, an outer cap 9 being provided having a central .hole I). through which passes the shank f of such a length as to allow movement of the cap corresponding to the displacement of the disk a The neck of the container is provided with a. ledge 2', and an undercut groove 9', though in some cases the groove may be omitted. lVhen the groove j is provided, the peripheral fingers have flanges 70 adapted to enter the groove.

The shank f is preferably attached to the disk at by a nut Z.

The above drawings are made to a scale twice the size of an actual cap for use on a petrol tank.
